Expensive for what it is, limited usefulness curious refrain ...

The calibration of printing gives the most visible effect. The calibration of the screen, while important is sometimes less necessary but all the same very effective (some screens are already not bad by default).

Calibrate a device ... is really very subtle. Has hardly seen the difference.

Warning: I mean no calibration and white balance - gray and white cards are more useful in practice.

Apart from that, the app is moderately well integrated in my opinion. That may be the fault of lightroom, perhaps x-rite. I think the product is too expensive for ergonomics offered. This is also the case for most calibration softwares (monitor and printer).

Basically, lack of integration and the subtlety of the results are that I do not use much color checker. In contrast, my Spyder (screen) all the time branch.

I was curious, I should abstain.
